To all whom it may concern:

Be it known that I, RICHARD E. MEYER, a citizen of the United States of America, residing at Detroit, in the county of Wayne and State of Michigan, have invented pier- X- plosive-Engines, of which the following is a specification, reference beinghad therein to the accompanying drawings.

This invention relates to an explosive engine and to an arrangement of the rotary valve mechanism therefor whereby a proper lubrication of the valve is obtained, together with avoidance of leakage and uncertain and noisy operation of the valve mechanism.

The invention consists in the matters hereinafter set forth, and more particularly pointed out in the claim.

In the drawings,

Figure 1' is a view partially in section and partially in. elevation, of a motor embodying features of the invention;

Fig. 2 is a view in transverse section thereof taken 'on or about line IIII of Fig. 1;

Fig. 3 is a view in detail of one form of valve;

Fig. 4; is a view in detail of another type of valve;

Fig. 5 is a view in detail of a modification ofthe'valve, and

Fig. 6 is a view in detail of a guard ring for securing the valve from deformation.

Referring to the drawings, cylinders l are mounted on a suitable engine base2 in which a crank shaft 3 is mounted in the usual manner. A countershaft 4, that is driven by any preferred type of positively acting mechanism from the main shaft 3 in proper timed relation thereto, operates annular gearing 5 through suitable ,pinions 6, each gearin being held in axial coincidence substantia ly with a cylinder by means of an upwardly extending sleeve 7 that rotatably engages in the cylinder and extends at least past inlet ports 8 and outlet ports 9 thereof.

I Preferably the interior of the annular gears is counterbored to receive the corresponding counterbored end portion of the sleeve with suitable connecting members indicated at 10. That portion of each sleeve which overlaps the ports of the cylinder is likewise ported as indicated at 11 in Fig. 3 and at 12 in Fig. 4, the ports being disposed in numbers according to the speed of the countershaft 4 rest of t and the type of engine, either two or four cycle. Whatever the arrangement of parts, the sleeve is longitudinally severed or split through the ports to a transverse segmental cut indicated at 13 lying Well below the port of the cylinder. Thus, under the action of the gases in the cylinder while under compression and in explosion, the sleeve tends to hug the cylinder closely and thereby prevents leakage around the ports, being its own packing. Preferably the severed portions with the ports and longitudinal cuts, are formed integrally with the body of the sleeve. The split and ported portion may, however, be split as indicated in Fig. 5 in which case the upper end portion of the cylinder is rabbeted and the split portion correspondingly counterbored, with a stud or groove 14 uniting the parts and securing the split portions between the longitudinal slots so as to permit free expansion and contraction of the ring.

Where the conditions are such that the through piston rod connections 19 of thecrank shaft. As a result of this construction an engine is obtained having a noislessly acting rotary valve that efiectively prevents leakage around the ports of the cylinders without the necessity of exterior packing rings and that is eflicient and positive in action. It is readil machined and assembledwith the he motor and forms a most eficient valve mechanism.

In the manufacture of the orted valve sleeve, it is preferable to ma e the walls of the sleeve, at the ported ends thereof, of

greater thickness than the remaining walls,

and then provide the thick walls with the ports and slits. The entire valve sleeve can then be turned down to a desired size and the ported andslitted end of the valve sleeve will possess a greater degree of resiliency or yieldability than if the sleeve w were ported and slitted after'being turned down preventing excessive yielding of the endor machined to a desired diameter. r portions thereof. 1 10 What I claim is In testimony whereof I aflix my signature In an explosive engine, ported cylinders, in presence of two Witnesses. a rotary valve sleeves therein, yieldable end RICHARD E.
